symfony/依赖注入与 symfony/console 冲突

Question

我有一个尝试更新的 magento2.2.6 网站。现在我遇到了这个错误：

symfony/dependency-injection v3.3.0 与 symfony/console[v4.1.5] 冲突。

我尝试查看了几个论坛和问题，也更改了一些版本，但没有好的结果。冲突问题仍然存在，我没有办法了。

要首先解决上述问题，您必须运行以下命令

第 1 步

composer config preferred-install dist
composer config sort-packages true
composer config prefer-stable true

第 2 步

composer require --dev friendsofphp/php-cs-fixer:~2.10.0 --no-update

第 3 步

composer require --dev friendsofphp/php-cs-fixer:~2.10.0 --no-update

第 4 步

php -r '$autoload=json_decode(file_get_contents("composer.json"), true); $autoload["autoload"]["psr-4"]["Zend\\Mvc\\Controller\\"]= "setup/src/Zend/Mvc/Controller/"; file_put_contents("composer.json", json_encode($autoload, JSON_PRETTY_PRINT|JSON_UNESCAPED_SLASHES));'

第 5 步

composer require magento/product-community-edition 2.3.0 --no-update

每一步我都做了，结果是这样的：
